Abstract: Let F be a p-adic field. We consider representations of Arthur type of a classical group G over F. By use of the Endoscopic Classification, Moeglin gave an explicit way to construct Arthur packets when G is a symplectic
Abstract : The Gibbs measure problem consists in constructing a unique global invariant flow supported by the measure itself. We address this problem for the cubic nonlinear Schrödinger equation posed on the two-dimensional sphere \(\mathbb{S}^2\). In this setting, concentration phenomena
L'assimilation de données vise à combiner de manière optimale les modèles dynamiques des systèmes physiques avec les mesures disponibles afin d'estimer l'état ou les paramètres du système. Dans de nombreuses applications, l'état ou l'espace d'observation est constitué de données de
We establish a convergence result for the approximation of low-regularity solutions to time-dependent PDE systems that have an involution structure similar to Maxwell's equations and the linear wave equations. The approximation is based on an explicit Runge--Kutta (ERK) time-stepping and
